Ahead of next week’s DVD and Blu-ray release of The Dark Knight Rises, Warner Brothers has released a behind the scenes video focusing on Batman’s aerial vehicle. The Bat, inspired by an Osprey prop jet, Harrier jump jet and Apache attack helicopter, weighs in at 3,000 pounds and measures 30 feet long and 17 feet wide. Co-producer Jordan Goldberg points out that the impact of a physical craft in its real scale is jaw-dropping, reminding viewers what it’s like to be a kid again, while Christian Bale lauds a design that’s fantastical but still grounded in reality. Check out the video below.
